Electric motor
An electric motor having a housing with a housing interior and also with an electronics compartment for a motor electronics system is provided. The housing has a housing base and a housing wall. The electronics compartment is arranged between the housing wall and a housing cover. The housing cover has a ventilation opening for venting the housing interior. The electronics compartment has a ventilation channel which is routed into the housing interior via the housing wall and has a channel connection piece which issues into the ventilation opening of the housing cover and is closed by an air-permeable diaphragm.
1. An electric motor comprising:
a housing with a housing interior for accommodating a stator and a rotor, which is arranged on a motor shaft so as to rotate with the rotor; and
an electronics compartment for a motor electronics system;
wherein the housing has a housing base and a housing wall which is arranged axially opposite the housing base,
wherein the electronics compartment for the motor electronics system is arranged between the housing wall and a housing cover that closes the electronics compartment,
wherein the housing cover has a ventilation opening for venting the housing interior, and
wherein the electronics compartment has a ventilation channel that is routed into the housing interior via the housing wall and that has a channel connection piece that issues into the ventilation opening in the housing cover and is closed by an air-permeable diaphragm.
2. The electric motor as claimed in claim 1 , wherein the diaphragm is arranged in the channel connection piece.
3. The electric motor as claimed in claim 1 , wherein the channel connection piece extends between the housing wall and the ventilation opening in the housing cover.
4. The electric motor as claimed in claim 1 , wherein the channel connection piece is integrally formed on the housing wall.
5. The electric motor as claimed in claim 1 , wherein the channel connection piece has an internal cone that widens in a direction of the ventilation opening in the housing cover.
6. The electric motor as claimed in claim 1 , wherein a seal is provided between the channel connection piece and the ventilation opening in the housing cover.
7. The electric motor as claimed in claim 1 , wherein the channel connection piece has a radially running partition wall with at least one wall opening.
8. The electric motor as claimed in claim 1 , wherein the channel connection piece has an axially running internal web.
9. The electric motor as claimed in claim 8 , wherein the internal web of the channel connection piece extends into the housing interior.
10. The electric motor as claimed in claim 1 , wherein a connection housing for plug connections of the motor electronics system is integrally formed on the housing wall.
11. The electric motor as claimed in claim 1 , wherein the housing, on a housing side which is averted from the housing base, has a housing flange for connection to a gear mechanism, in particular to a direct-shift gearbox or dual-clutch gearbox of a motor vehicle.
12. The electric motor as claimed in claim 1 , wherein the motor shaft is routed out of the housing via a housing opening which is provided in the housing base.
